ST. IGNACE, MICH. - Thousands are expected to take part in a Michigan Labor Day tradition by walking across the Mackinac Bridge.
Gov. Rick Snyder will lead the event, which starts 7 a.m. Monday on the north side of the nearly 5-mile-long span.
Buses will be available in Mackinaw City to take people across the bridge to St. Ignace to begin the walk.
About 40,000 people usually participate. It's the only time of year when the bridge linking Michigan's Lower and Upper peninsulas is open to pedestrians.
Activists protesting two oil pipelines in the Straits of Mackinac are expected to be on hand. Also scheduled is a swim across the straits organized by distance swimmer Jim Dreyer. Thirty-four people will compete, with the top-finishing man and woman receiving $20,000 each.
